I find the VV crowd to be very social. The entire ship is set up for socialization in the sense that there are literally chairs and loungers almost everywhere on the ship. It's a very chill ship during the day where you can hang with folks out by the (very tiny) pool. Or partake in the activities during the day.
One Sailor said it was like being in Summer Camp for Adults on our first voyage featured in the video link above from @cantgetin. That's kind of how it feels. Without the constraints of kids running around and 'being careful of conversation' around the little ones, there's a sense of freedom to just be you and have fun.
The biggest differences from the other lines are the mega-yacht feel of the ship, many inclusions so you're not having pay for a ton of extras, nobody upselling a drinks/dinner package, no photographers. Because all of the decks are essentially single story, the ship feels a lot smaller than it really is. You don't have that sense of scale with the multi story atrium or promenade or central feature of so many cruise ships that's more akin to a mall or Las Vegas resort. The ladyships are quite intimate and I think that leads to more social interaction.
Food is always subjective and since I produced that original video, The Wake is now a brunch only meal for us. We went to dinner there twice since we did that original video and it was underwhelming. Razzle Dazzle and Pink Agave are our two tops picks now and on a good night, Extra Virgin is amazing. We've really enjoyed Dine and Dash special dinner items the last few times we've been on the ships such as the butter chicken.
I have met folks from 18 to 80+ on the ships. If you are young at heart, you should really give VV a go.
